In a futuristic society being decimated by plague, a fascist movement seizes power and quarantines not only the plague victims, but anyone related to them. Rebels trying to assassinate a particularly reactionary senator stumble onto a computer programmer trying to track and eradicate the disease.

The Blakes have a rancher in the burbs, 2 kids, a mid-sized American car, a gas barbecue and lawn furniture. Dad works in an office, Mom does something vague and equally meaningless. They are exactly like all the people you see on the freeway every morning. Something happens - their young son gets sick.
